This commit cleans up for loop to use index to access

while iterating.

3d3c029471 nfs: add nodeserver within cephcsi
This commit adds nfs nodeserver capable of
mounting nfs volumes, even with pod networking
using NSenter design similar to rbd and cephfs.
NodePublish, NodeUnpublish, NodeGetVolumeStats
and NodeGetCapabilities have been implemented.

The nodeserver implementation has been inspired
from https://github.com/kubernetes-csi/csi-driver-nfs,
which was previously used for mounted cephcsi exported
nfs volumes. The current implementation is also
backward compatible for the previously created
PVCs.

d2bc9743f7 cephfs: add netNamespaceFilePath for CephFS
as same host directory is not shared between
the cephfs and the rbd plugin pod. we need
to keep the netNamespaceFilePath separately
for both cephfs and rbd. CephFS plugin will
use this path to execute mount -t commands.

b4acbd08a5 rbd: move radosNamespace to RBD section
As radosNamespace is more specific to
RBD not the general ceph configuration. Now
we introduced a new RBD section for RBD specific
options, Moving the radosNamespace to RBD section
and keeping the radosNamespace still under the
global ceph level configration for backward
compatibility.

c584fa20da rbd: use clusterID from volumeContext at nodestage
previously we were retriving clusterID using the monitors field
in the volume context at node stage code path. however it is possible to
retrieve or use clusterID directly from the volume context. This
commit also remove the getClusterIDFromMigrationVolume() function
which was used previously and its tests

2e8e8f5e64 rbd: fill clusterID if its a migration nodestage request
the migration nodestage request does not carry the 'clusterID' in it
and only monitors are available with the volumeContext. The volume
context flag 'migration=true' and 'static=true' flags allow us to
fill 'clusterID' from the passed in monitors to the volume Context,so
that rest of the static operations on nodestage can be proceeded as we
do treat static volumes today.

1f5963919f util: get clusterID for the passed in mon string
as part of migration support, the clusterID has to be fetched
from passed in mon. Because the intree RBD storage class only
got monitor and not `clusterID` parameter support. However, in
CSI, SC has the `clusterID` parameter support but not mon. Due
to that we have to fetch the clusterID from config file for the
passed in mon and use it in our operations. This adds a helper
function to retrieve clusterID from passed in mon string.

9d1e98ca60 rbd: check for clusterid mapping in genVolFromVolumeOptions()
This commit adds capability to genVolFromVolumeOptions() to fetch
mapped clusted-id & mon ips for mirrored PVC on secondary cluster
which may have different cluster-id.

This is required for NodeStageVolume().

We also don't need to check for mapping during volume create requests,
so it can be disabled by passing a bool checkClusterIDMapping as false.

GetMonsAndClusterID() is modified to accept bool checkClusterIDMapping
based on which clustermapping is checked to fetch mapped cluster-id and
mon-ips.
